I’ve just started dabbling in RC wireless flash for macro with the 60mm. I’m aware the FL300-R may not be the best way to go but I want to keep it simple and light, hence no sync cord. Camera E-M1 RC set to on. ‘A’ set to TTL…..this can be set between plus/minus 5 stops. Channel 1 Onboard flash set to ‘M’….this can be set between 1:1 & 1/128. ‘X’ sync 1/60 ISO200. Aperture priority se to f5.6. Flash FL300-R Off- camera with diffuser in place. RC set at ‘A’. Coming from Nikon where it all seemed to work as if by magic, the Oly system seems a bit on the trial/error side, or am I missing something. I have had a degree of success lighting the subject between 1:1 and 1: 4 but cannot get the balance with ambient correct. Are there some rules or is it just trial and error, a tutorial would be nice.
